Prefab Modernism by Werner Sobek

German architect/engineer Werner Sobek's R128 and H16 homes are prefab with a twist. These structures aren't available through a manufacturer; they're custom homes designed using lightweight, modular parts. The "prefab" part of these homes lies in their skillful engineering. R218 (shown above) is made from 100% recyclable, easy-to-assemble mortise and tenon joints and bolted joints, while the H16 is made from prefabricated architectural concrete...

Both homes (located in Germany) are green. In addition to its recyclable frame, the R128 has self-sufficient heating and energy systems powered by solar cells.

The glass panels are triple-glazed and have very low emissivity, making them energy-efficient while still providing incredible views.

The H16 is also tripled-glazed. It uses geothermal heating combined with solar panels to stay off the grid.

With geothermal heating systems, heat exchange is conducted deep within the earth through tubes that are naturally cooled during summer and warmed during winter.

Both buildings have a modernist aesthetic, but their material composition is very much of the 21st century. The prefab parts cut down on construction costs, while green energy systems have long-term benefits both environmentally and economically.
